I have the CWA-100 in my CL55 and it draws around 6.x amps at idle when the battery does 14.x V.
The pressure AFTER the intercooler was so high that you could use the bleed-ports hose as a garden hose for watering your plants ^^

CM30 works fine… You don't want to flow water through the system too fast. It does not give the fluid enough time to cool.
It's not about moving fluid as quickly as possibly its about pushing volume through the heat exchanger and letting it cool down enough before it gets heated up at the intercooler and comes back around.

Of course, but why would you want less volume movement than factory?

No, I'm not saying that.. I have not experienced any downside from CM30. I'm not aware of CM30 flowing less the stock. That does not seem very likely. But, who knows.. never the less they still work just fine. That is my point.

People replace their pumps because it is not functioning or on it's way out. CM30 is an excellent replacement.

I'm about to replace my CM30 with an 010 as part of my rebuild. Everything I have read from all the knowledgeable people mostly within this forum has confirmed the Bosch pump as the superior unit. Tests have been conducted where unbiased engineers have gone out of their way to determine flow pressure and quantity where the CM30 has trailed considerably.
Yes the CM30 was a good option as a replacement for the unreliable 002 but this was before Mercedes replaced it with the 010 now the choice seems obvious.

I am replacing my CM30 as it is finally toast after six years! A quality pump no doubt. I am however replacing it with the 010 as it is the best option today.

Bumping an old thread here, hoping for some advice/experience. During my E63 bumper swap I found that 1) the fuse for the IC pump was blown (and was incorrect at 7.5A), and 2) the PO had installed a Meziele WP136 and wired it to be ON with IGN, and 3) the WP136 appears to be seized/inop. I bench tested it with 12V and there's a slight thunk from it when power is applied, but it does not spin.
I already have a Bosch 010 pump ready to go, but in order to install the WP136 the PO shortened the inlet hose, replaced the wiring plug, and removed the factory pump hanger/clamp. So going to the 010 will take a bit of work (especially the plug part).
I'm running a VRP H/E and considering making it a split system. I've read conflicting info on whether the WP136 is "too much" for systems w/o a large reservoir tank, and the debate seems inconclusive from what I can read. I'm running a 76mm pulley and RaceIQ tune but otherwise power is effectively stock.
What would you choose in this situation? WP136 or Bosch 010?8.5.28.5.2

Well... yes lol. Of course. It holds on a 15A fuse, which is what it's supposed to be. But as I said, I bench tested the pump and it's locked up. But the circuit is hot with 12V whenever IGN is ON.

here is a link to the auction I bought mine on
Pierburg Hydraulic Pump Coolant 50W PN 7 01360 48 0 | eBay
it describes it as, "
Pierburg Hydraulic Pump/Coolant 50W pn. 7.01360.48.0."
on a related note, I was curious if my car would benefit from hard-wiring (to position 2, etc) the power for the IC pump. So I logged the power for a week or so and found for my car (2003 SL55 US version), the factory set-up is Ideal. Within the first 100 yards of driving from a cold start (my driveway, in the morning), the pump comes on and then stays on until a few seconds AFTER you shut the car off (with the only exception being that the pump will turn off if you come to a full stop when the IAT is below 70 F or so). If you start the car when it is warm, it comes on near-instantly.
Cheers,
Chris
